CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 781,578, dated January 31, 1905.

Application filed June 9, 1903. Serial No. 160,726.

Be it known that 1., ll nnnr H. \VAnN 1'1 n,a citizen of the United States, residing at Tacoma, in the county of Pierce and State of \Vashington, have invented certain new and useful improvements in Car-Brakes; and I do hereby declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an improved form of let-down brake-staff that can be operably supported and operated in either the vertical or the horizontal position.

A further object is to provide in such adevice means for supporting the uncouplinglever and also means whereby the several parts constitute washer-plates for the truss-rod of the car.

\Yith these objects in view, and others, my invention comprehends the construction, arrangement, and combination of parts, as hereinafter set forth with reference to the drawings and then pointed out in the claims.

Referring to the drawings illustrating an apparatus embodying my invention, Figure l is a front elevation. Fig. '2 is a plan view. Fig. 3 is a side elevation. Fig. l shows the supporting member in plan. Fig. 5 shows the support ing member in front elevation. Fig. 6 shows the bracket for retaining the brake-staff in a horizontal position. Fig. '7 shows the brakeshaft swivel. Fig. 8 shows the gravity-latch.

in the several views, in which the characters of reference indicate corresponding parts, to a supporting member or plate A on the bufferbeam of the air is secured a bracket B, having a journal portion B, in which is pivoted a swivel-socket The brake-staff D has its lower end portion rotatably carried in the socket O. This bracket has an arm B containing a slot B. arranged in vertical alinement with the socket U. \Vhen the brakestatf is in its vertical position. it lies in this slot. A gravity-latch E is pivoted on the arm B and is normally retained by its heavier portion I in the position shown in Fig. 2, so as to close the slot B and securely hold the brakestalf in the vertical position; but by swinging the arm w upward the arm (1 is swung away from the slot and the brake-staff may be moved out of the slot B. The brakestatf may be swung to the horizontal position, in which it is supported by a bracket F, having a supporting-arm f. The arm f forms, with the bracket, a circular hearingf", having an open upper side for receiving the brakestatl', and leading to this bearing is an outwardly-inclined slotf one wall f of which overhangs the open side of the bearing. Since the bearing f is in horizontal alinement with swivel-socket when the brake-staff is in its horizontal position, it follows that in order to lower the brake-staff into the bearing: the statf must be sprung slightly outward to permit its passing wall f, and when supported in the bearing this wall will prevent jars from lifting the staff out of position. \Yhen in this position, the wheel (I on the brake-staff lies at the side of the car and will permit freight on the car to extend beyond the end and onto an adjacent car having a similar let-down brakestatf. The brake-staff has a ratchet-wheel ll, that when in the horizontal position engages a pawl K, pivoted on the bracket F. \Vhen the brake-staff is in the vertical position, the ratchet-wheel ll engages a pawl 1C, pivoted on the bracket B. By mounting pawls K and K" on the journal members immediately adja cent bearings f and B" the ratchet-wheel on the brake-staff is reliably engaged by one or other of these pawls when the staff is in operative position. The bracket B also has a socket portion B, that serves as a washerplate for the truss-rod M, as shown in Fig. l. The bracket F has a socket F, that rotatably supports the uncoupling lover or arm N.

\Yithout limiting myself to the details of construction and arrangement shown and described, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a supporting member, a brake-staff rotatably mounted therein and arranged to he held in either a vertical or horizontal operative position, and a bracket for supporting the stall in a horizontal position, said bracket being adapted to support an uncoupling-lever.

2. The combination of a supporting member, a brake-stall rotatably mounted therein and arranged to be held in either a vertical or horizontal operative position, a bracket for supporting the stafi in a horizontal position, and an uncoupling lever mounted in said bracket.

8. The combination of a supporting member, a brake-staff pivoted thereon to occupy either a vertical or a horizontal position, a ratchet wheel on the brake staff, a slotted bearing for supporting the stafif in an upright position, a pawl pivoted adjacent the bearing, a bearing having an open upper side for receiving the stafi' when in a horizontal position, a pawl pivoted adjacent this bearing and positioned to engage with the ratchet-Wheel when the staff is in its horizontal position, and means for locking the staff in the slotted bearing in engagement with the first-named pawl.

4. The combination of a supporting member, a socket pivoted to the member, a brakestafi' carried by the socket and arranged to be supported in both the vertical and horizontal positions, a bracket arranged to support the brake-staff, when in the vertical position, a second bracket arranged to engage the brakestaff when in the horizontal position, and a gravity-latch arranged to lock the brake-staff in the first bracket, substantially as described.

5. The combination of a supporting member, a socket pivoted to the member, a brakestafi' carried by the socket and arranged to be I supported in both the vertical and horizontal positions, a bracket arranged to engage the brake-staff when in the horizontal position, a pawl carried by the latter bracket, a ratchetwheel on the brake-staff arranged to engage the said pawl, and a pawl on the supporting wheel when the brake-stafl' is in the vertical position, substantially as described.

6. The combination with asupporting member, a brake-staff, and a bearing carried by the supporting member and arranged to permit the rotation of the brake-staff therein in either a vertical or horizontal operative position; of a slotted bearing in vertical alinement with the first bearing when the brake-staff is in a vertical position and arranged to receive the staff when in such position, a third bearing in horizontal alinement with the first bearing when the brake-staff is in a horizontal position, said third bearing having an open upper side and arranged to support the staff when in such horizontal position, and an inclined slot leading to said third bearing and having one wall overhanging the open side thereof.

In testimony whereof I affix my signature in the presence of the subscribing witnesses.
